Shoujo Mahou Gaku Littlewitch Romanesque: Aria to Kaya to Kuro no Tou

An alternate world ruled by swords, magic, and monsters where four moons can be seen in the sky. The dark and chaotic twilight of the Age of Tower ended for this world called Stellamund and it entered the prosperous Age of Crown. But the wizards who triggered the great war during the Age of Tower no longer hold the power they used to have, and quietly researched the great magics that were lost, in a magical academy called Grimoire.
